FIELD OF THE INVENTION

[0001] The present invention relates to building materials, more particularly, to an inorganic wood-like material as a substitute for natural wood.

BACKGROUND OF THE INVENTION

[0002] It has been well realized by more and more people that trees play an important role to the environment of human beings. In order to reduce the consume of natural wood, it is necessary to seek and develop wood substitutes. It is an object of the present invention to provide an inorganic wood-like material made from cheap minerals and non-toxic recycled materials to change the history of the dependence of building industry on natural wood material.

SUMMARY OF THE INVENTION

[0003] The object of the invention is achieved by providing an inorganic wood-like material made from raw minerals, such as magnesite, magnesium chloride, lime powder, plant powder, glass fibre, protective mesh and processed to form a sheet as a kind of man-made inorganic wood substitute.

[0004] The inorganic wood-like material is made of hard raw minerals. Such material is fire-resistant (non-inflammable), water-proof, anti-corrosive, non-rust, durable and non-oxidation, non-deformable and cannot be eaten by mouse and moth. The material can be planned, sawed, can hold nails and screws tightly. The surface of the sheet is easy to be processed. The certificate of fire-resistance up to 4-hours under BS476PARTZO has been issued with respect to the material of the present invention.

DETAILED DESCRIPTION OF THE INVENTION

[0010] The features of the inorganic wood-like material of the invention will be described in details with reference to the accompany drawings.

[0011] With reference to FIG. 1, FIG. 1 shows an illustrating view of a first embodiment of the sheet made of the inorganic wood-like material of the present invention. The inorganic wood-like material comprises magnesite, magnesium chloride, lime powder, glass fibre, talcum powder and kaolin. Such raw materials are pulverized to particles or powder and then molded to form a sheet for use. In this embodiment, the laminated structure of the sheet includes three layers from the outer side to the inner side, i.e. a wear-resistant surface layer 11, an inorganic material layer 12, and a wear-resistant bottom layer 13, in which the composition and the ratio of the components of the two wear-resistant layers are same, which comprise 45%-60% magnesite, 15%-20% magnesium chloride, 5%-10% lime powder, 0.8%-10% glass fibre, 10%-15% kaolin. Beside the above-mentioned components in the same ratio, the inorganic material layer sandwiched between the wear-resistant surface layer 11 and the wear-resistant bottom layer 13 further comprises 18%-25% plant powder in order to be capable of holding nails tightly However, the other two layers cannot contain such plant powder to ensure that they are hard and wear-resistant.

[0012] With reference to FIG. 2, FIG. 2 shows an illustrating view of a second embodiment of the sheet made of the inorganic wood-like material of the present invention. In this embodiment, the laminated structure of the sheet includes five layers from the outer side to the inner side, i.e. a wear-resistant layer 21, an inorganic material layer 22, a heat and sound insulating layer 23, an inorganic material layer 24 and a wear-resistant bottom layer 25. Compared with the first embodiment in FIG. 1, the wear-resistant surface layer 21 and the wear-resistant bottom layer 25 are same as those layers 11 and 13; the inorganic material layers 22 and 24 are same as layer 12 of the above-mentioned embodiment. In addition, the sheet of the present embodiment further comprises a heat and sound insulating layer, so that it has an additional function of heat and sound insulation, which is advantageous over the first embodiment. The heat and sound insulating layer comprises similar components as those of inorganic material layer, except it further comprises 10%-20% glass wool. Such heat and sound insulating sheet is suitable for partition of apartment and cold storage.

[0013] With reference to FIG. 3, FIG. 3 shows an illustrating view of a third embodiment of the sheet made of the inorganic wood-like material of the invention. The laminated structure of the sheet comprises six layers from the outer side to the inner side, i.e. a wear-resistant layer 31, a protective mesh layer 32, an inorganic material layer 33, a heat and sound insulating layer 34, an inorganic material 35, and a wear-resistant layer 36. As compared with the second embodiment shown in FIG. 2, the difference is that the sheet of the third embodiment includes a protective mesh layer 32. Therefore, it is more difficult to break the sheet of the present embodiment. When being impacted by a hard object, the sheet will not tend to smash to pieces. It is tough. The main components of each layers are similar to those layers of the embodiment in FIG. 2, essentially containing magnesite, magnesium chloride, lime powder, glass fibre, talcum powder, kaolin and plant stalk powder, except that the protective mesh layer 32 includes 0.5%-0.8% protective mesh. Such laminated sheet is fire-resistant, water-proof, heat and sound insulating, cannot be eaten by mouse and moth, and provide enhanced protection against impact. It can be used repeatedly to form movable houses, garages, camps, enclosing walls for construction site, and so on. In order to become more sturdy, such sheet could be added 0.8%-10% enhanced formation additive when used as outer walls.

[0014] With reference to FIG. 4, FIG. 4 shows examples of the application of the sheet made of the inorganic wood-like material of the present invention As shown, the sheet of the invention can be used to make fire-resistant doors 41, doors 42, indoor and outdoor stairs and rails 43, movable toilets, houses and prefabricated houses/camps 45, roof-covers 46, fire-resistant plates 47, ceilings 48, plates, sandwich plates and floorings 49, pallets for transportation, and so on.

[0015] Since the material of the present invention has distinctive advantages, it will be widely accepted by industry and commerce.
